slashing is a mechanism which is specified for giving punishment or penalty to validators that are involved in manipulation of blockchain in anyway as you have explained some of the ways as well as I agree with you that it doesn't mean if one blockchain is using this mechanism then all blockchains would use this mechanism

You have also shared a real example of blockchain in which slashing mechanism we can see as well as you have also explain step by step and in easy words that how this mechanism applies on that blockchain which is very easy to understand for me and for everyone

Thank you so much for your wonderful words and for your comprehensive knowledge to share with us but there were some confusing lines in your post also I think you don't understand some of the questions in clear words but still the answers that you have provided are really appreciateable I wish you success and good luck
